The Q50's interior design continues to age gracefully, but age it does. It's the same basic design used since 2014, and it feels a bit behind the more modern, elegant environments in Audi and Mercedes rivals. But don't let that end your consideration. The Q50 is still a joy to drive. If you're looking for power, consider one of the Q50's turbocharged V6 engines. They deliver a jolt of pony car-esque thrill each time you dig into the pedal, especially in the Red Sport top trim. Infiniti also packs in plenty of standard features for you money.
Overall, the 2018 Infiniti Q50 isn't quite as polished as some rival sedans, but it stands as a desirable and stylish alternative to the status quo.
Edmunds' Expert Rating
Strong performance, plenty of premium features and a competitive price give the 2018 Infiniti Q50 a well-earned seat at the table with other refined and accomplished luxury sport sedans. Though better in some ways and inferior in others, the Q50 nonetheless is a desirable alternative.
Trim tested
Each vehicle typically comes in multiple versions that are fundamentally similar. The ratings in this review are based on our first drive of the 2018 Infiniti Q50 Red Sport 400 Sedan (turbo 3.0L V6 | 7-speed automatic | RWD).
Driving
The Q50 is a highly competent luxury sedan that's enjoyable to drive. It drives like a smaller, sportier car. The Q50 Sport trim demonstrates its true capability thanks to additional grip, while the Red Sport 400 is nothing short of a refined road hooligan.
Acceleration
The turbocharged four-cylinder engine's 208-hp output is subpar for the class, but real-world acceleration is certainly adequate. Both of the Q50's turbocharged V6 engines offer strong and satisfying power.
Braking
The brakes have a good feel and are easy to modulate, delivering consistent distances at the track. Panic-stopping distances are about average for summer-tire-equipped cars in this class.
Steering
The steering feels quick and precise and builds effort well, though it's a bit light for our tastes. The adaptive steering option on some Q50s is less impressive.
Handling
The Q50 3.0t Sport is a capable sport sedan. It inspires confidence with high levels of grip and composure. The Red Sport 400 amplifies these qualities considerably.
Drivability
The Q50 is a very pleasant sedan to drive. It exhibits good manners in typical driving and a natural sporting demeanor.
Comfort
The Q50 is comfortable and generally quiet, though road noise is still noticeable. The 2018 Red Sport 400 is a superbly comfortable touring car with excellent seats.
Interior
The Q50's cabin makes use of high-quality materials and sturdy construction, but the design hasn't changed much in nearly a decade. Conventional controls are within easy reach, but the touchscreen has some drawbacks. Still, it remains a pleasant and spacious place for driver or passenger.
Ease of use
Most systems are controlled via the split touchscreens, which can sometimes be confusing. Input reactions are quick and menus are intuitive, but the displays are often obscured by glare and fingerprints, especially with the newer protective glass.
Getting in/getting out
The Q50's low step-in height and wide seats facilitate easy entry and exit. As an added bonus, the doors swing open with surprising ease.
Roominess
The airy cabin and the contoured dashboard provide plenty of room up front. Six-footers can occupy the back seat with headroom to spare.
Visibility
The forward view is expansive through the windshield, but the higher beltline and relatively high rear decklid reduce the view over your shoulder and out the rear window. The optional surround-view monitor eliminates any guesswork in tight spaces.
Quality
Even though it's showing its age, the Q50 maintains high standards for materials and craftsmanship. Compared to newer luxury sport sedans, the Infiniti looks and feels about average for the class.
Utility
The Q50's cargo capacity is decent for the class, but interior storage for your personal items is somewhat lacking by contemporary standards. The trunk space is adequate, though the wide opening makes for easier loading.
Technology
It takes a little time to get used to the dual touchscreens, but most users will find the menus intuitive. Reactions to inputs are quick, and updates to the Infiniti InTouch system have kept it relevant.
Which Q50 does Edmunds recommend?
The 2018 Infiniti Q50 with the 3.0t engine delivers strong performance and comes with a lot of standard features at a reasonable price. Choosing between the Luxe or Sport trim depends on your driving style and appetite for nicer features (although many Sport features are available as options). If nothing else, the Luxe gives you a little more flexibility with options that aren't exorbitantly priced, but do come bundled in large packages.

The Q50 Hybrid Luxe comes in one trim level similarly equipped to the 3.0t Luxe, but it also borrows from the Sport and Red Sport 400 features. Some extra features, including adaptive cruise control and a premium Bose audio system, are also standard on the Hybrid.
Many of the extra features found on the Red Sport are available as options on the lower trims. Depending on the trim level, other key options an adjustable suspension, additional driver aids and a premium audio system.

My original lease for the 2014 Infiniti Q50 is reaching the end. Based on my past 3+ years experience driving the Q50 on a daily basis, I have decided Q50 is worthwhile to own for the long term. After reviewing the Q50 2014 vs 2018 model, I decided to purchase the 2018 Q50 due to a newer engine, improved onscreen response time, updated SOS communication module, etc.). For someone that … drives 90 miles everyday, the active safety features (adaptive cruise control, lane keep assist, etc.) is literally a life saver, and help to avoid accidents.
Fun to drive

2018 INFINITI Q50 RED SPORT 400 4dr Sedan (3.0L 6cyl Turbo 7A)
Coming from a 2015 gs350 fsport. This ride is definitely louder but feels much sportier. You can hear the tires on the road. That being said I love everything else about the car. The technology and the dual screens i actually love. The steering with 1 button adjustment feels just as good as any car I have owned. It is fast I haven't even needed to cross 3000 RPMs yet to get to 80. I … havent depressed the pedal past halfway yet! The value particularly on a lease for a 50-60k car is second to none. 400 horses and gas mileage better than my lexus. Love this car how it drives and how it looks. The only comfort features I miss but dont need is the power folding side mirrors and the power closing trunk.
I was in the market for a luxury sedan. I need this for my personal use, as I do own a minivan used for kids and errands. I wanted to keep my expenses within a reasonable range, and hence eliminated the German cars from my search. From the Japanese luxury sedans, the Infiniti was more fun to drive and engaging. Infiniti then gave me a good deal, which settled the matter for me. There is … a lot of chatter about the dual screen and jnfotainment system, but I found it easy to use. I actually like having touchscreens, and can get to anything I want with a couple of quick clicks.
My car came with all the bells and whistles. I don’t think anyone should get a luxury sedan without highly desired options that come in a few uncomplicated packages
Stupid Fast!

2017 INFINITI Q50 Red Sport 400 4dr Sedan AWD (3.0L 6cyl Turbo 7A)
I have almost 10,000 miles on my 2017 Q50 Red Sport so I figured it was about time to write a review. I have had it for 10 months and driven in snow, rain and dry conditions. Mountains and flat ground. The thing has been great in all conditions, even in a mini blizzard! You have to watch the throttle in bad weather, or use the economy or snow modes but otherwise it handles great. I … find myself going over the limit a bit more often when accelerating on an on-ramp, it just gets to speed so quickly if you aren't paying attention, even faster if you have it in sport or sport+ mode. I typically drive around in standard mode. I initially used the economy mode but realized it didn't seem to make a big difference in fuel economy. Speaking of, I average 22-24 MPG with a good mix of city and highway. I play with the speed a bit but I'm not racing every car I pull up next to at a stop light either. I have had it back to the dealer three times. First was for the Bluetooth system. It would not connect properly to my old LG G4 even though they advertised it would. They went through the Bluetooth system and couldn't find anything and finally told me to go away that there wasn't anything they could do for me. Now with my new (Samsung S8) there haven't been any issues. Second trip was for the first oil change. Third trip was due to a notice I got in the mail about a computer re-programming (no big deal). Otherwise I haven't had any issues. I was a littler nervous about the run flat tires and no spare. I got a nail in one of the tires and saw that it was $465/tire for the OEM tires. Luckily the nail didn't puncture the air chamber and I didn't have to replace the tire. There are cheaper run flats but I have been impressed with the tires, not sure I want to spend that for replacement tires when that time comes. Overall for being a fairly large car, it handles well and has a stupid amount of acceleration, even at highway speeds. I love the flat torque curve. I was a little worried about having some buyers remorse but so far I have been super happy with the car!
October 2002 Update: Have around 55,000 miles on the car now. Nothing has really changed from my initial thoughts. Few sets of tires (Bridgestone Driveguard seem to work well on it and get good mileage). Have take a couple trips and driven in a lot of snow/ice with no issues. It does take a little getting used to the handling in the snow but once you get the feel for it there aren't really any issues. Still very happy with the purchase.
We have a limited number of reviews for the 2018 INFINITI Q50, so we've included reviews for other years of the Q50 since its last redesign.
